Independent Predictors of Mortality Among Patients With NAFLD Hospitalized With COVID-19 Infection.

The impact of the coronavirus disease 2019 (COVID-19) pandemic among patients with chronic liver disease is unknown. Given the high prevalence of nonalcoholic fatty liver disease (NAFLD), we determined the predictors of mortality and hospital resource use among patients with NAFLD admitted with COVID-19 by using electronic medical records data for adult patients with COVID-19 hospitalized in a multihospital health system who were discharged between March and December 2020. NAFLD was diagnosed by imaging or liver biopsy without other liver diseases.

Assessing the Viability of the Methylsulfinyl Radical-Ozone Reaction.

Although integral to remote marine atmospheric sulfur chemistry, the reaction between methylsulfinyl radical (CH SO) and ozone poses challenges to theoretical treatments. The lone theoretical study on this reaction reported an unphysically large barrier of 66 kcal mol for abstraction of an oxygen atom from O by CH SO. Herein, we demonstrate that this result stems from improper use of MP2 with a single-reference, unrestricted Hartree-Fock (UHF) wavefunction.

Development of 17 microsatellite markers in the federally endangered species (Asteraceae).

Premise: Microsatellite markers were developed in the federally endangered species (Asteraceae) to evaluate species boundaries with closely related congeners within the genus.

Methods And Results: Using Illumina data, 17 primer pairs were developed in populations of . The primers amplified motifs from tri- to hexanucleotide repeats with one to 17 alleles per locus.

Hepatic sonic hedgehog protein expression measured by computer assisted morphometry significantly correlates with features of non-alcoholic steatohepatitis.

Background: Hepatic expression of Sonic Hedgehog (SHH) is associated with Non-alcoholic fatty liver disease (NAFLD) and development of Non-alcoholic steatohepatitis (NASH). Hepatic SHH detection increases with the diagnosis of NASH. This pilot study was designed to confirm that staining for SHH is useful in NASH diagnosis and determine whether quantification of staining by computer assisted morphometry (CAM) can be used to assess severity of ballooning degeneration.

Prototypical Transition-Metal Carbenes, (CO)Cr═CH, (CO)Fe═CH, (CO)Ni═CH, (CO)Mo═CH, (CO)Ru═CH, (CO)Pd═CH, (CO)W═CH, (CO)Os═CH, and (CO)Pt═CH: Challenge to Experiment.

Transition-metal carbenes are useful in organometallic chemistry due to their demonstrated use as catalysts in carbon-carbon bond-forming reactions. Yet the prototypical transition-metal carbenes, consisting of a single metal center doubly bonded to a methylene ligand and surrounded by carbonyls, have been elusive to experimental synthesis. This theoretical work examines the structures and properties of nine prototypical transition-metal carbenes.
